Answer:
Calcium metal is liberated at cathode.
Chlorine is obtained at anode.
Explanation:
Electrolysis is a process in which electric current is passed through a substance which results in a chemical change i.e., loss or gain of electrons (oxidation or reduction).
During electrolysis of CaCl2
At anode: 2Cl⁻ → Cl₂ + 2e⁻ ( oxidation takes place at anode)
At anode: Ca²⁺ + 2e⁻ → Ca ( reduction takes place at cathode)
RESULT: During electrolysis of calcium chloride, calcium metal is liberated at cathode. Chlorine is obtained at anode.
